1513The ___________ minicomputer was designed & built from 1965 to 1980It was the first mass market mini-computer developed for educational purposeAdditionally it possesses two attributes i.e. continuing interest in it's architecture and implementation14The famous _______________________ computer, the first commercial (that is, mass produced) computer. In the 50's, it was also the first computer to employ magnetic tape. Many people still confuse a picture of a reel-to-reel tape recorder with a picture of a mainframe computer. 15The forefather of today's all-electronic digital computers is _______________________ built at the University of Pennsylvania between 1943 and 1945 by two professors, John Mauchly and the 24 year old J. Presper Eckert, who got funding from the war department after promising they could build a machine that would replace all the "computers", meaning the women who were employed calculating the firing tables for the army's artillery guns. 16Harvard Universitys ________________________ was the first programmable digital computer made in the U.S. But it was not a purely electronic computer it was constructed out of switches, relays, rotating shafts, and clutches. The machine weighed 5 tons, incorporated 500 miles of wire, was 8 feet tall and 51 feet long, and had a 50 ft rotating shaft running its length, turned by a 5 horsepower electric motor.

He reinvented Babbage's concept of programming and decided on his own to employ binary representation 18_____________________________ is the The Father of Computers1822 : His great invention Difference engine was to perform mathematical calculationsIt was fully automatic and commanded by a fixed instruction program 1842 The Analytical Engine was a automatic machine. It could do 60 addition per minuteThe idea of analytical engine didnt take physical form but served as a base for modern digital computers19In 1801 Frenchman ______________ invented a power loom that could base its weave (and hence the design on the fabric) upon a pattern automatically read from punched wooden cards, held together in a long row by rope.20In 1642 ________________________ , at age 19, invented the Pascaline as an aid for his father who was a tax collector. Pascal built 50 of this gear-driven one-function calculator (it could only add) but couldn't sell many because of their exorbitant cost and because they really weren't that accurate (at that time it was not possible to fabricate gears with the required precisionGood luck and Thank you..Wavin' FlagIXA`M`PParty251210.17 - lemonFamily Affair MixIXA`M`PParty185610.3 - lemon
